DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] See also Figure 1-6 , the utility model provides a technical solution:

[0028] An anti-collision vehicle head for UV printing comprises a vehicle head body 1, and UV frames 10 for installing UV heads 14 are arranged on the left and right sides of the vehicle head body 1, and a protective device for protecting the UV heads 14 is arranged on the UV frames 10;

[0029] The protective device includes a fence mechanism arranged at the periphery of each UV head 14, the fence mechanism includes multiple groups of telescopic rods 2 and a group of anti-collision rods 3, a rotating shaft frame 11 is longitudinally rotatably installed on the UV frame 10, multiple groups of telescopic rods 2 are vertically installed side by side at the bottom of the rotating shaft frame 11, the bottom telescopic ends of the telescopic rods 2 are fixedly installed on the anti-collision rods 3, the anti-collision rods 3 are horizontally longitudinally arranged and lower than the height of the UV head 14, a sensor is arranged at the bottom of the anti-collision rod 3, a micro switch 15 is installed on the UV frame 10, the trigger end of the micro switch 15 is located on the rotation path of the telescopic rod 2 toward the UV head 14, and the output end of the sensor and the micro switch 15 controls the driving component of the vehicle head body 1;

[0030] When working, first, multiple groups of telescopic rods 2 and anti-collision rods 3 cooperate to form a fence-like outer side protection. In the vertical direction, the anti-collision rods 3 cooperate with multiple groups of telescopic rods 2 to provide vertical downward pressure buffering, and are equipped with sensors to prevent collisions and vertical buffering of accidental vertical collisions. The telescopic rods 2 and anti-collision rods 3 as a whole form a fence mechanism to prevent lateral hard collisions. The rotation connection method is mainly used for the situation where the fence mechanism rotates toward the UV head 14 side and hits the more expensive UV head 14. Therefore, a micro switch 15 is set in the inner direction of the fence mechanism, that is, toward the UV head 14. Figure 4 As shown, the trigger end of the micro switch 15, that is, the micro switch paddle is against the outer wall side of the telescopic rod 2. When the telescopic rod 2 rotates toward the UV head 14, the micro switch 15 will be triggered to generate a potential signal. Here, the output potential signal of the sensor and the micro switch 15 cooperates with the controller in the vehicle head body 1. The controller controls the drive component to immediately stop the movement of the vehicle head body 1, thereby performing timely shutdown maintenance for the impact event. The controller and drive component here are conventional settings and will not be repeated here.

[0031] Example 2

[0032] Wherein, the telescopic rod 2 includes a telescopic sleeve 20 and a telescopic connecting rod 21, the telescopic connecting rod 21 is slidably inserted into the bottom of the telescopic sleeve 20 through a telescopic spring 22 fixed at the inner top, a limit block 23 is fixed at the top of the telescopic spring 22, and the limit block 23 is clamped inside the telescopic sleeve 20 through a trigger limit mechanism, a limit ring 25 is fixed at the inner top of the telescopic sleeve 20, and a limit spring 24 with upward elastic force is directly installed on the limit ring 25 and the limit block 23, and a trigger pressure block 29 for triggering the action of the limit mechanism is slidably installed on the outer wall of the telescopic sleeve 20, and when the fence mechanism is about to hit the UV head 14, the trigger end of the micro switch 15 presses the trigger pressure block 29, and the trigger limit mechanism releases the limit connection of the limit block 23, and the limit spring 24 pulls the limit block 23 to slide upward;

[0033] The limiting mechanism includes a trigger groove 26 provided on the inner wall of the telescopic sleeve 20, the trigger pressure block 29 is slidably inserted into the trigger groove 26, a bite groove 28 is rotatably installed in the trigger groove 26, the rotation axis of the bite groove 28 is perpendicular to the central axis of the telescopic sleeve 20, a built-in spring for maintaining the inclination of the bite groove 28 is installed in the trigger groove 26, the side wall of the limiting block 23 is provided with an oblique upper mouth-shaped bite groove 28 for embedding the bottom corner of the bite groove 28, and the inner end of the trigger pressure block 29 slides against the top end of the limit rotating rod 27;

[0034] During operation, when 3 is hit toward the side of the UV head 14, 3 rotates around the rotating shaft frame 11 as a whole. At this time, although the micro switch 15 has been triggered, due to the delay effect of inertia, the telescopic rod 2 and the anti-collision rod 3 will still rotate toward the UV head 14. At this time, the micro switch 15 The micro paddle will press the trigger pressure block 29 inwards under the limit state, such as Figure 6 As shown, at this time, the trigger pressure block 29 rotates the limit rotating rod 27 counterclockwise, and the bottom end of the limit rotating rod 27 slides out from the bite groove 28, and the limit block 23 is no longer limited. The limit spring 24 will instantly pull the limit block 23 upward, and the telescopic connecting rod 21 will quickly retract upward, and the entire 3 will also be lifted upward to a safe height. The inertial rotation path will no longer hit the UV head 14, especially the bottom port position of the UV head 14, thereby providing further double insurance protection for the UV head 14.

[0035] A reset rod 13 is vertically slidably mounted on the top of the rotating shaft frame 11, the reset rod 13 slides into the telescopic sleeve 20, the reset rod 13 slides through the limit ring 25 and is fixed to the limit block 23, and a reset button 12 is fixedly mounted on the top of the reset rod 13;

[0036] During operation, after the limit block 23 contacts the limit and is driven upward, a reset rod 13 is provided to facilitate resetting the limit block 23. After the limit block 23 is pulled upward, the reset button 12 pops out. It is only necessary to press the reset button 12 downward, and the reset button 12 will press the limit block 23 back to the trigger groove 26 through the reset rod 13 until the bottom of the limit rotating rod 27 is re-engaged in the bite groove 28, and the reset is completed.

[0037] Wherein, the anti-collision rod 3 is made of deformable material;

[0038] During operation, the anti-collision rod 3 can be made of a rubber rod, which has a certain contact strength and can be deformed under a huge impact, thereby improving the protection effect.
